HORSESHOE-MACHINEQ Specification of Letters Patent.

' Patented June 4, 1 907.

Application filed Decembe 3, 1904- Serial No. 235,336.

To all whom it may concern.-

Be it known that I, ARTHUR SMYIH, a citizen of the United States, residing at Easton, in the county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in Horseshoe-Machines, of which the following is a specification.

This invention relates to improvements in cutters for removing the fin from the backs of creased or punched billets used in the manufacture of machine-made horseshoes.

In an application for patent filed by me April 11th, 1903, Serial No. 152,105, is described a machine for creasing billets. Forming a part of that machine is a cutter for removing the fin from the back of the billet.

My present invention relates to an improved form of cutter for the same general kind of machine.

The object I have in view is to produce a device which will effectively remove the fin, and to so arrange the cutter that it will not be displaced by irregularities or wavy conformations of the billet.

Other objects are to reduce the friction of the cutter upon its spindle, and to render the parts accessible for adjustment or repair.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which,

Figure 1 is a plan vie-w of the device. Fig.

i 2 is a section taken on the lines 22 of Fig. 1

and showing a'portion of the creased billet within the device; and Fig. 3 is a section taken on the lines 3-3 of Fig. 1, showing the position assumed by the creased billet.

In all of the several views like parts are designated by the same numerals of reference.

In carrying out my invention, I provide a base 1, having an elevated table 2, which serves as a support for the creased billet 3. A funnel shaped casing 4 arranged above the table constitutes a chute, and serves as a guide for the billet, this casing having inclined walls 5 and an inclined top 6 so that the billet will be properly directed and presented for the action of the cutter.

The cutter 7 is in the form of a disk and is mounted upon ball bearings upon a spindle 8 which can be oscillated to bring the cutter.

into engagement with the top of the billet, the said spindleconstituting a movablesupport for the cutter. The spindle is pivoted at 9 to ears 10, 10, depending from the bottom of the base 1, so that it maybe inclined to the position shown in dotted lines in Fig. 2. As shown in Fig. 2, the spindle is shouldered at 11, and has upon the shoulder a loose ring 12 which constitutes a roller. Above thering is another shoulder 13 upon which is a washer 14 for holding the ring 12 in place. This washer may be secured by means of a pin 15. Above the washer 14 the spindle is screw threaded to support the ball cup 16 and a lock nut 17. The cutter 7 is provided with a cone 18 and a row of balls 19 in the cup forms the lower portion of' the bearing. balls and the cutter is held in engagement with the creased billet, when the billet is in the position shown in dotted lines in Fig. 2, by means of a spring 19. The upper end of the spring is engaged by means of a cup 20 having ball races therein and carrying a row of balls 21 and by means of which the spring is compressed.

A cone 22 engages with the balls andforms the upper portion of the bearing, and a lock nut 23 retains the cone against accidental displacement. The peripheries of the cones 22 and the cup 16 may be milled as shown in Fig. 3 for purposes of adjustment, the cup 16 being adjustable to accommodate different sizes of bullets, and the cone to adjust the upper bearing. The spindle 8 is inclined upon its pivot to bring the edge of the cutter into engagement with the top of the billet by means of a cam plate 2 1, having an inclined surface 25, and a straight surface 26. This cam plate is engaged between the ring 12 and a roller 27. The roller 27 is supported upon a stud 28, mounted within a slot 29 in the plate 1 to permit of adjustment for use with creased billets of varying depth. The cam plate 24 passes through an opening 30 in the table 2- The cone is depressed upon the' and one extremity is provided with a support for-a pin 31. Mounted upon this pin 31 is a lever 32, having bifurcated extremities 33 and with its other end pivoted at 34 to the plate the position shown in Fig. 3 and a spring 37 is provided for inclining the spindle 8 to the position shown in full lines in Flg. 2. An

elevated flange 38 on the table 2 is provided for guiding the creased billet upon the table. This flange 38 is cut away at 39 adjacent to the roller 35, to allow the roller to be engaged by the billet.

The operation of the mechanism described is as follows :The billet 3 after being creased will be found to have a fin upon one edge opposite to the creases. The creased billet is fed into the funnel shaped opening of the chute 4, by suitable mechanism, the rollers 41, 41, which constitute feeding mechanism, serving as an illustration, and passes along the table 2 being guided thereon by means of the flange 38. One edge of the billet will engage with the roller 35, and move the lever 32 upon its pivot 34, sliding the cam plate 24 against the tension of the spring 36; The incline 25 on the cam plate will engage with the ring 12 on the spindle 8, (the other side of the cam plate bearing against the fixed roller 27), and will incline the spindle 8 upon its axis 9, tilting the cutter 7 until its edge comes into contact with the upper side of the creased.

billet. The billet continuing to be fed along the table 2 the cutter will engage with the top of the billet and turning upon the spindle will shear and cut OE and remove all of the fin. The flange 38 on the table will prevent sidewise displacement of the billet from the resisting action of the cutter. It isto be noted that the cutter is rotated entirely by engagement with the billet, which is fed against the outter, and the cutter is not rotated by other mechanism. As soon as the billet passes through beyond the cutter, the spring 36 will retract the cam plate 24 and the spindle 8 will be restored to its normal position by means of the spring 37, thus elevating the edge of the cutter toward the advancing billet, and presenting the parts inposition to re ceive a fresh billet.

By employing a cam plate with the inclined portion 25, and the straight portion 26, if the spindle has been inclined, by the action of the cam plate, it will remain in such inclined position irrespective of slight variations in that edge of the billet which engages with the roller. Slight irregularities in the upper surface of the billet will be compensated for by means of spring 19 which will be compressed or expanded as necessary. By arranging the roller 35 to engage with the edge of the creased billet, the parts are rendered much more accessible than where the roller engages with the top. The ball bearings described prevent the cutter from binding and always insure the rotation of the cutter.

It is to be understood that the springs 36 and 37 may be omitted in case it is desired that the cam plate and spindle be moved by manual means.
